SPECIFICATION formingpart of Letters Patent No. 711,938, dated October 28, 1902.

Application filed February 21, 1902. Serial No. 95,012. (No model.)

To (1J/Z whom, it nea/y 0071106772,.-

Be it known that I, CHARLES H. CAsrEE, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvementsin Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to iigures of reference marked thereon, which form a part of this specification.

This invention refers to a press that is continuous in its operation and at the same time is simply constructed to insure ease of operation.

The class to which the invention refers more particularly is rotary presses, in which the articles to be partially dried are turned in a drum, especially such materials as brewers grains, dac., and are thereby deprived of a large amount of moisture previous to their introduction into a drier.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a sectional view on line 1 l in Fig. 2, and Fig. 2 a similar View on line 2Y 2 in Fig. 1. Fig. 3 is a perspective of one of the blades. f

Similar reference-numbers as applied in the several views refer to like parts.

A frame 10 is placed on both sides of a casing 11,which is supported by the frames,which also provide bearings for the driving mechanism, which receives its power rom the pulley 12. A shaft 13 supports a wheel14, which has slots 15 radially arranged, and in these slots are blades or paddles 16. The wheel 14 is arranged eccentrically to the casing 11, and in the casing is a concentrically-arran ged slot 17, which allows of blocks 1S, which are placed on the ends of the blades 16, to run therein, and as the blades are of equal length keep their outer ends near or at the inside edge of the casing 1l. These blocks are fitted on a pintle on either side of the blades, as evident from Fig. 2, and as the wheel 11 is of the same width as the inside of the casing chambers are formed between the paddles, the casing, and the wheel, which are enlarging and diminishing as the eccentric wheel14 revolves,

the paddles being maintained in the positions by the slot and the pintles allowing them to adjust themselves to the angles assumed. On the bottom ofthe casing is arranged a strainer 19, which is secured to a draining-plate 20, provided with outlets 21, and which plate is supported by the side clamps 22, which tit over and run on the casing, as in Fig. 2. In the transverse center of the plate 201 provide teeth which form a rack which can be actuated bya worm 23, and a shaft 24 and handwheel 25 may be employed to operate it.

When in operation, the material that is to be pressed is introduced into the press from the top and is carried by the paddles in the direction of arrow a in Fig. 1. As the wheel is eccentric, the chambers on the periphery of the wheel become smaller as they proceed toward the strainer, and the moisture is slowly squeezed out, as the machine has a slow speed. The casing being cut away at 26, the end of the strainer releases the partially-dried material and it leaves the press. When it is desired to exert more pressure on tle material, the hand-wheel and Worm are moved, which would move the strainer to the position shown in dotted lines in Fig. 1, and the'chamber at the releasing-point would be smaller, and the grain, dac., would be more thoroughly drained. g

The presses of this class as previously. made have no regulating means, and the press must be kept completely full to drain properly, as if onlye'nough grain or other material is introduced into a chamber to fill it at the discharging-point no pressure is exerted. Inv this construction if the chambers are not filled the strainer can be moved up to contract the opening, and the chamber at that point is smaller and the material is squeezed sufficiently.

The liquid forced out through the strainer is carried to the outlets 21, which may be connected to suitable piping.

This construction provides a rotary press with adjustable pressure, which is easily and quickly regulated.

Having thus described my invention,what I claim is 1. A press, comprising a casing, an eccentric wheel, paddles sliding in ways in said wheel, means for maintaining the paddles IOO concentric to the casing, a strainer slidably arranged in the bottom of the casing, to regulate the outlet.

2. In a press, an eccentric Wheel provided with sliding paddles concentric to the casing, a strainer slidably arranged in the bottom of thecasing to regulate the pressure and outlet.

3. In a press, an eccentric Wheel provided with sliding paddles concentric to the casing, a strainer slidably arranged in the bottom of the casing to regulate the pressure and outlet, and means for moving said strainer.

4. In a press, an eccentric wheel provided with sliding paddles concentric to the casing, a strainer slidably arranged in the bottom of the casing to regulate the pressure and outlet, teeth on said strainer and a Worm-wheel to actuate the same,substan tially as set forth.

5. In a press, comprising a casing, an eccentric Wheel provided with sliding paddles,

means to maintain the paddles concentric to the casing, a straining mechanism slidably arranged in the bottom of the casing, to regulate the pressure and outlet, substantially as set forth.

6. A press, comprising a casing, an eccentric Wheel provided with sliding paddles, means to maintain the paddles concentric to the casing, a straining mechanism slidabl;7 arranged in the bottom of the casing', to regulatey the pressure and outlet, a rack on said mechanism and a Worm-wheel actuating said rack, substantially as set forth.

In testimony that I claim the invention set forth above I have hereunto set my hand this 13th day of February, 1902.

CHARLES II. CASPER.
